How do I get the size of different screen ?

If I'm not wrong, I found some research that iFrame on iOS is weird since iOS 4.x. They have made that it resizes to the size of the content so you aren't confused about scrolling inside a page (you scroll down the page, and suddenly, you start scrolling inside the iFrame and not down the page – that's not what iOS users want).

This should work to stretch the sprite to fullscreen:

set width = viewportright(0)-viewportleft(0)

set height = viewportbottom(0)-viewporttop(0)

Hi,

this is working for width but not for height

any advice please ?
